What’s Changed?

Canada has reduced the lowest federal personal income tax rate: 15% to 14.5% for 2025, and 14% starting in 2026 and thereafter. This rate directly impacts the value of non-refundable tax credits, such as the basic personal amount, medical expense credit, caregiver credit, etc. (canada.ca)

How It Impacts You

  • More disposable income: Lower withholding if you're on payroll—savings of up to $420/year for individuals, or $840 for dual-income families. (canada.ca)
  • Tax credit reductions: Non-refundable credits are worth less dollar-for-dollar when multiplied by a lower tax rate. So if you rely on those credits, the benefit shrinks.
  • Marginal relief for low-income brackets: If you’re near the bottom tax bracket, your tax savings can matter more (e.g. someone making $35,000 vs $80,000).

Tax Planning Strategies

Adjust Payroll and Installments

• Ask your employer to adjust your tax withholdings to reflect the new rate to avoid overpaying throughout the year. • If you make instalment payments, recalculate them based on the new rate.

Leverage Tax Credits Differently

• Credits that are refundable aren’t affected by your tax rate, so non-refundable ones should be maximized early. • Itemize and track eligible expenses (medical, caregiver, volunteer firefighter, etc.) to ensure you’re getting full credit.

Income Timing and Splitting

• If possible, shift or defer income to 2026 when the lower rate (14%) is in full effect. • Use income splitting strategies (e.g. spousal loans) for families, where allowable, to spread taxable income across lower marginal rates.

Example

Sarah earns $40,000/year. Under the old 15% rate, a $1,000 medical expense non-refundable credit saves her $150 in tax. Under 14%, that credit now saves $140—a $10 drop. However, her overall tax payment drops elsewhere, so her take-home improves more than in many previous years.

Action Items

  • Review your latest pay stub or installments and ensure you’re taxed at the lower marginal rate.
  • File all deductions and credits you’re entitled to—non-refundable credits lose value unless claimed.
  • Consider meeting with a tax professional to adjust tax planning for the next fiscal year.
